Genes affected
SGTA (HGNC:10819): (small glutamine rich tetratricopeptide repeat co-chaperone alpha) This gene encodes a protein which is capable of interacting with the major nonstructural protein of parvovirus H-1 and 70-kDa heat shock cognate protein; however, its function is not known. Since this transcript is expressed ubiquitously in various tissues, this protein may serve a housekeeping function. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.758G>A (p.G253D) alteration is located in exon 10 (coding exon 9) of the SGTA gene. This alteration results from a G to A substitution at nucleotide position 758, causing the glycine (G) at amino acid position 253 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
